How to make a livery pack

So on youtube we can find all sorts of videos explaining how to make a livery for a car, but I can not seem to find a video on how to make one livery for multiple cars, such as a livery pack. Because all car templates are set up differently. So does anyone know how to make a livery pack for multiple cars?

I dont think you can make a pack, you will need to get every car template and make same livery for them in ytd file if I understood you right.Cars have different shapes and etc would be hard to fit 1 livery for many cars
